Sherman F. Corb'eil, Clifton, Ariz. Application November 22, 1343,Serial No. 511321 2 Claims. (Cl. l57-G) This invention relates to a tiretool, and it is primarily an object of tool of this kind forseparating'a stuck tire from the rim.

It is a common custom to pry a pneumatic tire off its rim by using aflat bar and hammering which requires a considerable amount of time andlabor and in many instances results in injury-to the tire and moreparticularlyin such instances where the tire has become stuck or rustedto the rim. It is a further object of the invention to provide a toolwhich can be employed in a manner to more conveniently and expeditiouslyaccomplish such removal.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved tiretool whereby certain important advantages are attained, as will behereinafter more fully set forth. 9

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying drawings,wherein:

Figure 1 is a view in side elevation of a tire tool constructed inaccordance with an embodiment of my invention in its initial or startingposition, the associated tire and rimbeing shown in section;

Figure 2 is a view partly in elevation and partly in sectionillustrating certain of the parts in a second position;

Figure 3 is a top plan view of the tool;

Figure 4 is a bottom plan View;

Figure 5 is a sectional view taken substantially on the line 5-5 ofFigure 1; and

Figure 6 is a view taken substantially on the line 6-6 of Figure 1.

In the embodiment of the invention as illustrated in the accompanyingdrawings, the improved tool comprises a relatively long head I havingone end portion continued to provide a hand grip 2. The head I at itsouter end portion is provided with an opening 3 in which extends theouter extremity of a relatively short angularly disposed portion 4 of arelatively long lever 5.

This outer extremity of the portion 4 is provided with a transversesleeve or barrel 6 which receives and freely turns on a pivot pin Idisposed transversely through the head I and passing through suchopening 3. The portion of the head I immediately adjacent the inner endof the opening 3 is inwardly beveled or chamfered, as at 8, tofacilitate the desired swinging movement of the lever 5 with respect tothe head I.

the invention to provide a The lever 5 inwardly of, but in relativelyclose proximity to, the portion 4 is provided with a longitudinallydisposed slot "9 through which passes an outstanding post It] carried bythe head I. This post Ill outwardly of the lever 5 is provided with across head II whereby the extent of outward movement of the lever 5 islimited. Interposed between the lever 55 and the head I is an expansiblemember I2, herein disclosed as a coiled spring surrounding the post Ill.

The inner portion of the head I has extending outwardly therefrom at theside thereof remote from the lever 5 the relatively short arms I4arranged in parallelism and spaced apart transversely of the head I. Theouter extremities of these relatively short arms M are provided with therelatively long jaws I5 extending away from the head at an obliqueangle.

The head I' between the short arms I4 is provided with an opening Itthrough which freely passes a lOng arm ll. This arm I1 is of such lengthas to have one end portion extending beyond the outer ends of theshorter arms I4 and the jaws I5 carried thereby when the long arm I1 isat the limit of its endwise movement as effected by the movement or thelever 5 toward the head I.

The end of the arm II adjacent to the lever 5 is provided with anoutstanding headed member I8 which is freely disposed through a slot I9in the lever 5 and extending lengthwise thereof. This headed member 18coacts with the lever 5 in a manner whereby backward and forwardmovement of the arm I1 may be had upon corresponding swinging movementof the lever 5.

The opposite end portion of the arm H or that end portion between theshort arms I4 is also provided with a relatively long jaw 20 similar to,and extending in the same direction as, the jaws I5 and an expansiblemember or spring I2 which serves to normally maintain the jaw 20 in aposition directly between the jaws I5, so that in the use of the toolall three of the jaws I5 and 20 may be forced between the side of apneumatic tire T and the rim R.

The inner portion of the head I inwardly of the short arms I4 andimmediately adjacent to the hand grip 2 is provided with a throatopening 2| traversed by a pin 22 extending transversely through the headI. This pin 22 is positioned above and forwardly with respect to theouter or free ends of the jaws I5 and 20. Disposed through this opening2| to one side of the lever 5 and mounted upon the pin 22 is a thrustlever 23. The outer end portion of this thrust lever 23 carries arelatively long thrust arm 24 which extends in the same generaldirection as the hand grip 2 and overlies the same at one side of thelever 5. The thrust lever 23 extends beyond the opposite side of thehead I or that side of the head from which the short arms H extend adistance sufficient to engage inwardly of the rim R when the thrust arm24 is in an outward position, so that as this thrust arm 24 is swungtoward the hand grip "2, the result-ant action of the thrust lever 23 bycontact with the rim R will force the jaWS l5 and 20 between the rim Rand the tire T while said jaws are in their normal side by sideposition. After this opera.-v tion, the lever 5 is forced inwardlytoward the hand grip 2, resulting in the jaw 20 being moved beyond thejaws 15 with resultant compression of the adjacent portion of the tire Tto disengage such portion of the tire from the rim. This is especiallyadvantageous when such portion of the tire is stuck or rusted to therim.

From the foregoing description it is thought to be obvious that atiretool constructed in accordance with my invention is particularlywell adapted for use by reason of the convenience and facility withwhich it maybe assembled and operated.

What is claimed is:

1. A tire tool comprising a relatively long body forming a head andhaving a longitudinal exten'-. sion at one end forming a hand grip, apair of spaced rigid arms rigid with and projecting from one side of thehead intermediate the ends thereof and terminating in two tapered jawsdirected obliquely to the length of the head, the head having an openingbetween the arms, a, longer rigid arm slidably positioned 'in saidopening between the first arms and having a blunt end extending beyondthe opposite side of =t'heheadsa id longer arm being movabletransversely of the head parallel with the spaced arms, the other end ofsaid longer arm terminating in a tapered jaw angled to parallel thefirst jaws, a lever pivotally attached at one end to the head adjacentto the end of the head remote from thehand grip and extendinglongitudinally of the body over said blunt end of the longer arm forcoaction with the hand grip, resilient means constantly urging the leveraway from the hand grip, and means coupling the lever with the saidblunt end of the arm for effecting movement of the second mentionedtapered jaw in one direction upon pressure of the lever toward the handgrip. 2. A tire tool, comprising a relatively long body formed at oneend to provide a longitudinally extending hand grip, a pair of armscarried by the body and extending perpendicularly thereto, said armshaving integral, relatively long, tapered jaws extending therefrom in adirection toward the hand grip in a line oblique to the length of the"body, one of said arms being fixed and the other arm the fixed arm, athrust lever pivoted intermediate its ends to the bodyfor oscillation onan axis extending transversely of the body between the arms and the handgrip, said =thrust lever being of a length from the oscillation axis toits free end to position said free end in close proximity to the ,freeends of said jaws, a thrust arm carried upon the ther end of said thrustlever and located upon the other side of the body from the jaws adaptedfor co-action with the .hand grip for the 'actuationof the thrustlevertoward the free ends of the jaws, and means ior eifecting the cr m nt 9fh @01'4'21? rm 9 m en o the Je c rr d th eb tive to h other in .a lineperpendicular to the body.
